PD6710/22 ISA-to-PC-Card (PCMCIA) Controllers  
12.0  
ATA Mode Operation  
The PD67XX PC Card interfaces can be dynamically configured to support a PC Cardcompatible  
ATA disk interface (commonly known as IDE) instead of the standard PC Card interface. Disk  
drives that can be made mechanically-compatible with PC Card dimensions can thus operate  
through the socket using the ATA electrical interface.  
Configuring a socket to support ATA operation changes the function of certain card socket signals  
to support the needs of the ATA disk interface. Table 17 lists each interface pin and its function  
when a PD67XX card socket is operating in ATA mode. Refer to application note AN-PD5,  
Configuring PCMCIA Sockets for ATA Drive Interface, for more information.  
All register functions of the PD67XX are available in ATA mode, including socket power control,  
interface signal disabling, and card window control. No memory operations are allowed in ATA  
mode.
